The objective of this paper is to present a formant frequency estimation method, developed with a view to track small variations due to involuntary vocal tract movement. The formant frequency estimation is based on the instantaneous frequencies obtained by means of a complex wavelet transform and is synchronised with the glottal cycle. Results for synthetic speech signals show the precision of the formant frequency estimation method. Results are presented for speech signals from both normophonic speakers and speakers with Parkinson's disease.
